residual output (AIN-output). In situations where AI4-input is used as an input
signal the corresponding information is available on the non-calculated output
(AI4) on the SMAI function block. Connect the signals to the AxRADR
accordingly.
For each of the analog signals, Operation = On means that it is recorded by the
disturbance recorder. The trigger is independent of the setting of Operation, and
triggers even if operation is set to Off. Both undervoltage and overvoltage can be
used as trigger conditions. The same applies for the current signals.
If Operation = Off, no waveform (samples) will be recorded and reported in graph.
However, Trip value, pre-fault and fault value will be recorded and reported. The
input channel can still be used to trig the disturbance recorder.
If Operation = On, waveform (samples) will also be recorded and reported in
graph.
The analog signals are presented only in the disturbance recording, but they affect
the entire disturbance report when being used as triggers.
Binary signals
M12155-162 v9
Up to 352 binary signals can be selected to be handled by disturbance report. The
signals can be selected from internal logical and binary input signals. A binary
signal is selected to be recorded when:
• the corresponding function block is included in the configuration
• the signal is connected to the input of the function block
Each of the 352 signals can be selected as a trigger of the disturbance report
(Operation = On). A binary signal can be selected to activate the red LED on the
local HMI (SetLED = On).
The selected signals are presented in the event recorder, event list and the
disturbance recording. But they affect the whole disturbance report when they are
used as triggers. The indications are also selected from these 352 signals with local
HMI IndicationMask = Show/Hide.
Trigger signals
M12155-164 v2
The trigger conditions affect the entire disturbance report, except the event list,
which runs continuously. As soon as at least one trigger condition is fulfilled, a
complete disturbance report is recorded. On the other hand, if no trigger condition
is fulfilled, there is no disturbance report, no indications, and so on. This implies
the importance of choosing the right signals as trigger conditions.
A trigger can be of type:
• Manual trigger
• Binary-signal trigger
• Analog-signal trigger (over/under function)
